Metallization is one of the finishing processes in textile treatment that can produce multifunctional effects.
The present study dealt with the development of an antibacterial polyester-knitted fabric via facile and green
impregnation of silver nanoparticles (SNPs). This was done by applying a polymeric foundation on the polyesterknitted
fabric by simply dip-coating in the aqueous solution of dopamine. Then the SNPs were in situ fabricated and impregnated
on the surface of polydopamine-modified polyester-knitted fabric in an aqueous solution of AgNO$_3$ at room temperature.
Thus, a multi-functional finishing of polyester-knitted fabric was done. The Fourier transform infrared spectroscopy
was done to confirm the polymer attachment. Scanning electron microscopy equipped withenergy dispersive
X-ray was done to confirm the presence of SNPs on treated fabric. The crystallography of the treated surface
was examined by X-ray diffraction. The antibacterial properties of treated fabrics against broadspectrum bacterial
strains were investigated and found significant.
